Madrid Creates 'Acoustic Protection Zone'

In downtown Madrid, music floats through the air, amateur musicians playing for money. Sadly, many are not that good, but the city is on the case. To shield residents from mediocre musicianship, it's created an Acoustic Protection Zone. Buskers who wish to perform will be talent-tested. A panel will issue permits to those who have what it takes. The rest will be booted off the stage or, in this case, the sidewalk.
